Ginzburg–Landau approach to the Gross–Neveu model: success and failure
Abstract The phase diagram of the Gross–Neveu model in 1+1 dimensions is studied using Ginzburg–Landau expansion. It predicts several features of the exact phase diagram correctly even at low orders. It is shown that increasing the order of the expansion improves the accuracy of the crystal phase ex...
